Data Views to Route All Requests, Irrespective of
the Target DN of the Request

This section describes a data view that routes all requests to a data
source pool, irrespective of the target DN of the request. This data view
is called the root data view. The root data view is
created by default when an instance of Directory Proxy Server is created.

The example in this section has multiple data sources that contain the
same set of subtrees. The data sources are data-equivalent and pooled into
one data source pool for load balancing. A data view is configured with a
base DN at the rootDSE, represented as “ ”. Figure 22–3 shows an example deployment.

Figure 22–3 Example Deployment That Routes All Requests to a
Data Source Pool, Irrespective of the Target DN of the Request

Because the base DN of the data view is the rootDSE, the data view encompasses
the base DN of all possible requests. All requests are
forwarded to the data source pool, irrespective of the target DN or whether
the data source contains an entry for the request.

If Directory Proxy Server receives a request with a target DN that does
not exist in the data source, the request is forwarded to the data source
pool. The data source that responds to the request returns an error.
